Hi @rohit782192
You can configure the input tool to the file format FLAT ASCII format. The attached example is doing it for a flat file with length delimeted columns (a common case), if you want to check out.
To assign column breaks, place your cursor where the break should be.
Select the column-break lines to delete them.
Use the scroll bars beneath the file preview to reveal additional data within the file and assign the appropriate column breaks.
